Polyester conveyor belts, also called EP conveyor belts. whose tension resistant body is canvas woven by polyester in warp and polyamine in weft, The belts have the characteristics of low elongation in warp and good troughability in weft. good water resistance , good wet strength, no mould it is suitable for medium, long distance and heavy-load transportation of materials . Because of the high initial modulus of polyester the belts can choose a relative low safety factor.Introduction Specification and technical data of multi-ply polyester conveyor beltFabric typeFabric structurePly thickness (mm/p) Ply Thickness (mm/p)(N/mm) Strength series(mm) Cover thicknessWidth mmLength mmWarpWeft2ply3ply4ply5ply6plyUpperUpperPolyester (EP)Polyester (EP)Polyamine (P)EP-800.61602403204004801.5∼120∼4.5400∼2500≤300EP-1000.75200300400500600EP-1501300450600750900400∼2500EP-2001.140060080010001200EP-2501.25500750100012501500EP-3001.35600900120015001800800∼2500EP-3501.4510501400175021001000∼2500EP-4001.55160020002400EP-5001.7200025003000Conver properties of the belts TypeMpa ≥Mpa ≥mm2 ≤Change Rate of tensile strengh and elong after aging%H24450120-25∼+25D18400100-25∼+25L15350200-25∼+25Adhesion and elongation of the belt Item.
